On my digidash the oil pressure has always read full pressure unless at idle when it drops down to 1/2 or 3/4. However, went for a long run today (about 200miles) and as I was heading back home I noticed that at 60mphish in 5th the pressure was reading 1/2. When I accelerated it shot back up again.
I then pulled into a garage for a drink and noticed at idle only the 1st curvy bit was lit!
When I got home I left the car on the drive for 30mins then had a look underneath. Pre journey there was no leaks at all - now there was an oil leak, even if it was slight. Couldn't see where from tho. Checked dipstick and level was ok.
How should the oil pressure behave (on a newly rebuilt engine)?
Do you think i have a problem?
